17 different 'instruments' sampled from the Roland TB-303 analog synthesizer.
This synthesizer is used a lot in 'modern' dance music / techno mostly for
bass-lines and arpeggiators. The 'typical' TB-303 sound has a closing filter
with plenty of resonance.

If you modify these sounds, you may extend this exception to your version of the sounds, but you are not obligated to do so. If you do not wish to do so, delete this exception statement from your version.
